All About Achilles Tendonitis

Overview
This nagging injury can be long-lasting if not treated - and if your running form needs some work. The name Achilles is said to be a combination of two Greek words that together mean ?grief of the people.? The injury that bears that hero?s name, in honor of his only weakness, certainly aggrieves many runners, with Achilles tendinitis accounting for around 10 percent of running injuries. Technically, Achilles tendinitis is acute inflammation of the tendon that runs along the back of the ankle. Pain in that area for longer than a couple weeks is not really tendinitis anymore. Athletes, however, tend to characterize any pain along the tendon above the back of the heel as Achilles tendinitis. Achilles tendinitis can be confused with other injuries, such as heel problems, but the hallmark sign is if you?re pinching the Achilles and it?s really sore.

Causes
The two most common causes of Achilles tendonitis are Lack of flexibility and Overpronation. Other factors associated with Achilles tendonitis are recent changes in footwear, and changes in exercise training schedules. Often long distance runners will have symptoms of Achilles tendonitis after increasing their mileage or increasing the amount of hill training they are doing. As people age, tendons, like other tissues in the body, become less flexible, more rigid, and more susceptible to injury. Therefore, middle-age recreational athletes are most susceptible to Achilles tendonitis.

Symptoms
Symptoms of Achilles tendonitis include, pain in the back of the heel, difficulty walking, sometimes the pain makes walking impossible, swelling, tenderness and warmth of the Achilles tendon. Achilles tendonitis is graded according to how severe it is, mild - pain in the Achilles tendon during a particular activity (such as running) or shortly after. Moderate - the Achilles tendon may swell. In some cases, a hard lump (nodule) may form in the tendon. Severe - any type of activity that involves weight bearing causes pain of the Achilles tendon. Very occasionally, the Achilles tendon may rupture (tear). When an Achilles tendon ruptures, it is said to feel like a hard whack on the heel.

Diagnosis
Examination of the achilles tendon is inspection for muscle atrophy, swelling, asymmetry, joint effusions and erythema. Atrophy is an important clue to the duration of the tendinopathy and it is often present with chronic conditions. Swelling, asymmetry and erythema in pathologic tendons are often observed in the examination. Joint effusions are uncommon with tendinopathy and suggest the possibility of intra-articular pathology. Range of motion testing, strength and flexibility are often limited on the side of the tendinopathy. Palpation tends to elicit well-localized tenderness that is similar in quality and location to the pain experienced during activity. Physical examinations of the Achilles tendon often reveals palpable nodules and thickening. Anatomic deformities, such as forefoot and heel varus and excessive pes planus or foot pronation, should receive special attention. These anatomic deformities are often associated with this problem. In case extra research is wanted, an echography is the first choice of examination when there is a suspicion of tendinosis. Imaging studies are not necessary to diagnose achilles tendonitis, but may be useful with differential diagnosis. Ultrasound is the imaging modality of first choice as it provides a clear indication of tendon width, changes of water content within the tendon and collagen integrity, as well as bursal swelling. MRI may be indicated if diagnosis is unclear or symptoms are atypical. MRI may show increased signal within the Achilles.

Nonsurgical Treatment
Initial treatment consists of medication and ice to relieve the pain, stretching and strengthening exercises, and modification of the activity that initially caused the problem. These all can be carried out at home, although referral to a physical therapist or athletic trainer for further evaluation and treatment may be helpful. Occasionally a walking boot or cast may be recommended to immobilize the tendon, allowing the inflammation to settle down. For less severe cases or after immobilization, a heel lift may be prescribed to reduce stress to the tendon. This may be followed by an elastic bandage wrap of the ankle and Achilles tendon. Orthotics (arch supports) may be prescribed or recommended by your physician. Surgery to remove the inflamed tendon lining or degenerated tendon tissue is rarely necessary and has shown less than predictable results.


Surgical Treatment
There are three common procedures that doctor preform in order help heal the tendinitis depending on the location of the tendinitis and amount of damage to the tendon, including: Gastrocnemius recession - With this surgery doctors lengthen the calf muscles because the tight muscles increases stress on the Achilles tendon. The procedure is typically done on people who have difficulty flexing their feet even with constant stretching. Debridement and Repair - When there is less than 50% damage in the tendon, it is possible for doctors to remove the injured parts and repair the healthy portions. This surgery is most done for patients who are suffering from bone spurs or arthritis. To repair the tendon doctors may use metal or plastic anchors to help hold the Achilles tendon in place. Patients have to wear a boot or cast for 2 weeks or more, depending and the damage done to the tendon. Debridement with Tendon Transfer - When there is more the 50% damage done to the Achilles tendon, and Achilles tendon transfer is preformed because the remain healthy tissue is not strong enough. The tendon that helps the big toe move is attached to give added strength to the damaged Achilles. After surgery, most patients don?t notice any difference when they walk or run.

Prevention
The following measures can significantly reduce the risk of developing Achilles tendonitis. Adequately stretch and warm up prior to exercise. Warm down and stretch after exercise. Choose footwear carefully and use footwear appropriate to the sport being undertaken. Use orthotic devices in footwear to correctly support the foot. Exercise within fitness levels and follow a sensible exercise programme. Develop strong, flexible calf muscles.
